by hits to raid actually not sure. for 1st raid my clan get ~170k points, and we didn't managed to kill 2nd, but we finished with ~280 or 290k points few times. give up when ~10-15% left on 2nd. we aren't top clan, and only few peoples have really good gear. and also that fact that you can't res there really matters. only salva and feather can help. but not everyone have shirts/talismans or feathers. and in 2nd (and probably higher stages) ton of minions who "autoassist" literally can kick you from one throne corner to another..

for second raid can help only iss with MI for dd's or few good evi who attack only when sm and that barrier who protect from range attacks.. otherwise most time you spend knocked down instead of attacking boss, and ofc tanks should do their job with kiting those minions..idk about rest bosses, didn't saw how they looks.. or there is only 3?
